Money is a tool we use to achieve a goal. Different people have different strategies for what to do with money.
Some spend everything on consumer goods or recreational activities, such as enjoying a meal in a restaurant or going to a cinema. Others are in a situation where they can’t save money at all. They have to live from paycheck to paycheck. Such people are said to be living hand-to-mouth.
Other people save money for a rainy day. They can keep their money at home or in a bank. Still, other people invest their money. They invest in safe places such as properties or precious metals, or stocks of large companies. Some invest in risky places such as cryptocurrencies. They hope to gain a large return on their investments.
